Paper、plastic、aluminum composite packaging is a packaging system that uses food specific cardboard as the base material, and is composed of polyethylene, paper, aluminum foil, and other composite paper packaging materials. It is a high-tech food preservation method, which refers to a packaging technique in which liquid food is sterilized for a short period of time before packaging, and then filled and sealed in a sterile environment under sterile conditions, that is, in a sterile environment where the packaging, and packaging auxiliary equipment are all sterile.
Feature
The capacity is generally around 180-2000ml. There are two types of applications: refrigerated packaging and room temperature packaging. Refrigerated packaging includes milk rooftop packaging, bricks, pillows, and juice rooftop packaging. Room temperature packaging includes sterile bricks, sterile pillows, and hot filled roof packs. The common paper plastic aluminum composite sterile packaging materials in the market mainly include four types of raw materials: cardboard, polyethylene, aluminum foil, and ink. Cardboard does not directly contact the contents of the packaging, but it is an important component of the packaging, accounting for about 75% of the entire packaging weight. The main function is to enhance the stiffness and hardness of the packaging after molding. Food grade polyethylene in sterile polyethylene packaging accounts for about 20% of the total weight of the packaging, and its main function is to block liquid leakage and microbial invasion. The weight of aluminum foil in sterile packaging only accounts for about 5% of the entire packaging. Its main function is to avoid light and block air permeability, keep the content from oxidation, reduce nutritional loss, and maintain a fresh taste. The weight of ink in sterile packaging is negligible, but it is very important for hygiene and safety. The main inks used for packaging and printing of dairy products and beverages in the market are solvent based inks and water-based inks.
Application Area
Paper plastic aluminum composite packaging is widely used in the processing of liquid dairy products, plant protein beverages, fruit juice beverages, alcoholic products, and drinking water. Aseptic packaging materials can be used to package products such as milk, fruit juice and beverages, alcohol, water, tomato products, soups, desserts, nutritional foods, and other products.
Develop
Paper plastic aluminum composite packaging has a good development trend in China due to its advantages and freshness. There are also two main reasons for this. Firstly, China's milk production is mainly in the north, and the consumption of milk in the south is higher than that in the north. Therefore, the packaging of milk at room temperature is particularly urgent. Secondly, with the improvement of national living standards, the demand for fruit juice drinks and tea drinks has been increasing year by year. Therefore, the demand for sterile packaged food is constantly increasing. In the next few years, the production and quality of sterile composite packaging materials in China will greatly increase, and it is possible to enter well-known domestic dairy groups such as Yili, Mengniu, and Guangming in the future, thereby breaking the monopoly of bankrupt enterprises. The development prospects of sterile packaging are very promising, and there is an urgent need for policy support from relevant national departments. Sterile packaging products are fiercely competing in the low-end market, and the domestic high-end sterile packaging market is being handed over to multinational enterprises.
